Add GitLab CI support

Add .gitlab-ci.yml file that supports building the docker container
on all branches, but only push to Docker Hub updated images when
code is committed to master and update the latest tag for the image
when a tag (release) is created.

Simplify docker file by just installing yottadb to /opt/yottadb/current
instead of installing to a version directory and symlinking

.gitlab-ci.yml
